摘要

In this study, 0.5%, 1.0%, 2.0% and 4.0% weighted SiO2 powders were added to bronze-based materials, which are used as friction materials. Blended powders were mixed in three-dimensional mixers to provide a homogeneous mixture. Powders were pressed under pressure of 350 MPa using a single-action press. Pressed samples were sintered at 820 degrees C, for 20 minutes, in ammonia atmosphere. Sintered samples are tested in a wear test device. Wear and friction coefficient tests are carried out on sintered samples. As revealed, with higher amounts of SiO2, the friction coefficient is increased, and the wear ratio is decreased.
